This feature request comes about 196 days to early.
It is perhaps worth considering on April 1, but not in September.

Why do you want to enable it, then remove it? What's your motivation for

IMO, an os level function such as os.clear_terminal(fd) should only
support terminal/console devices and would be implemented in
Modules/posixmodule.c. Higher-level behavior and support for IDEs
belongs in shutil.

Not an educator, but since no-one seems to have mentioned this: I often use
"os.system('clear')" for quick and dirty terminal animations, eg. to debug
a maze solver for some competitive coding challenge... Not much of a use

The IPython terminal has used Python Prompt Toolkit since version 5, so PPT
would be my default choice for any shell or console applications (though I
haven't used it for a few years).

'clear' should also leave the cursor in the upper-left position, which cannot
be gotten by writing a bunch of line feeds.

I occasionally find it useful to clear the screen when doing

I teach a lot. But it's adults, and ones who have at least a little bit of
programming experience (perhaps in a different language, but something).
I've never had anyone request a "clear screen" command. Of course, I
usually use Jupyter notebooks for teaching, so I'm not sure what that would

Note that clearing the screen (command window these days) IS common -- at

It's not uncommon for C++ tutorials etc, to refer to using:

The python equivalent would be:
